Noise optimized air distributor
View Patent ↗An air distributor is provided that includes, but is not limited to a perforated body, insertable at a joint between a first air duct, which extends in one direction, and a second air duct, that extends in a second different direction, to redirect air flowing in the first air duct into the second air duct and to reduce low frequency high volume noise.
1. An air distributor, comprising:
a first air duct extending in a first direction;
a second air duct extending in a second direction;
a joint between the first air duct and the second air duct;
a body adapted for insertion at the joint and adapted to deflect an airflow in the first air duct into the second air duct;
a plurality of perforations in the body adapted to pass a component of the airflow, the plurality of perforations located in an area of the body where the airflow initially impacts upon the air distributor, the plurality of perforations being configured such that the component of the airflow passing through the plurality of perforations generates small vortices thereby reducing low frequency noise generated by the airflow exiting from the first duct;
a base end of the body that points into the first direction when in an installed position; and
a first top end and a second top end of the body adapted to extend partially into the second air duct.
2. The air distributor according to claim 1 , wherein the plurality of perforations is located on at least a fraction of a surface of the body.
3. The air distributor according to one of the claim 1 , wherein the body has a shape of at least one of the first air duct or the second air duct.
4. The air distributor according to claim 1 , wherein the body is a tubular shape body.
5. The air distributor according to claim 1 , wherein the body is a plate shaped body.
6. The air distributor according to claim 1 , wherein the tubular body is a Y-shaped body.
7. The air distributor according to claim 1 , wherein the tubular body is a V-shaped body.
8. An air distributor, comprising:
a first air duct extending in a first direction;
a second air duct extending in a second direction, substantially perpendicular to the first direction;
a joint between the first air duct and the second air duct;
a body adapted for insertion at the joint and adapted to obliquely deflect an airflow exiting from the first air duct into the second air duct at an initial airflow impact area;
a plurality of perforations in the body adapted to pass a component of the airflow, the plurality of perforations located in the initial airflow impact area;
a base end of the body that points into the first direction when in an installed position; and
a first top end and a second top end of the body adapted to extend partially into the second air duct.
9. The air distributor of claim 8 , wherein the plurality of perforations is configured such that at least the component of the airflow passing through the plurality of perforations generates vortices that induce high frequency noise.
10. The air distributor according to claim 9 , wherein the plurality of perforations is located on at least a fraction of a surface of the body.
11. The air distributor according to one of the claim 9 , wherein the body has a shape of at least one of the first air duct or the second air duct.
12. The air distributor according to claim 9 , wherein the body is a tubular shape body.
13. The air distributor according to claim 9 , wherein the body is a plate shaped body.
14. The air distributor according to claim 12 , wherein the tubular body is a Y-shaped body.
15. The air distributor according to claim 12 , wherein the tubular body is a V-shaped body.
